6. Assume a Role with Cognito
Create an instance of your
Mobile Analytics Application
Create->Record->Submit Events
Submitting Events: Android Example

7. Submitting Events: JavaScript Example

8. In-App Purchases: iOS

9. Demo: Mobile Analytics

10. Deliver: SNS

11. Provider
(APNS, GCM, MPNS,…)
Token Request
Amazon
SNS
Platform Application
“Token”
Platform Endpoint
- Upload Certificates, API Keys, etc.
Upload Token
- AKA “Create Platform Endpoint”
Platform Application Lifecycle

12. APNS

App Creation (developer.apple.com)
• BundleID
• Push Enabled
Certificate Creation
Provisioning Profile
Test Connection
Configuring Platform Applications
GCM
Components
• Google Developer Project
• Mobile App
• Backend Application (SNS)
Credentials
• Sender ID (aka “Project Number”)
• API Key (authorization)
• HTTP header or XMPP auth
request
• AppID

13. Demo: SNS

14. Authorization
Cognito Identity
- Create Unique Identities
- Roles
- Authenticated
- Unauthenticated
- Temporary, limited
credentials
Cognito User Pools
- Fully managed User
Directory
- Federate with Identity
- Pass to API Gateway
- Sign-up/Sign-in Workflows

15. Fine-grained control
Send to Mobile Analytics
Sync Datasets across devices
Add Token to SNS
Add email/phone to SNS

16. Provider

17. Demo: Cognito

18. Native
Interrogates app lifecycle
- Background queue filled with
Session and Custom Events
- Session events batched & sent
Backgrounded time > AWSValueSessionResumeDelay
- Custom events sent anytime
- Best practice: use
onPause, onStop,
onResume
SDK Session Management
Web
Configure default session length
Force event submission anytime
Window.localStorage ensures
persistence through browser/tab
exiting

19. Enhancing JavaScript Sessions
Debate: Apples vs. Oranges?
Modern browsers offer visibilitychange() event:
https://developer.mozilla.org/en-US/docs/Web/Events/visibilitychange
extendSession()
stopSession()

20. Delivery Status
Written to CloudWatch Logs
- 2-week graph of Sent vs Delivered
- Publishers can also write to
CloudWatch w/ custom metric
Tracking Metrics
Application Events
Publish to Topics
- Lambda, HTTP/S, etc.

21. Publishing to SNS

22. iOS
// if your app had to be launched. A particular key is set in options to
specify that a push notification was received-
application:didFinishLaunchingWithOptions:
// if you app was already running in the background
application:didReceiveRemoteNotification:
Metrics: Open on Push
Android

23. Demo: Custom Metrics

24. Personalization
Engagement is all about personalization
- Automatic push if they installed but never did action X
- Push to group of users (Topic) with a custom message
- “Discount today click here!”
- Push to individuals with customized messages
- "Hey John we noticed you looked at product X but didn't
purchase"

25. Tying it all together: Request tracking
Amazon API
Gateway
Amazon
SQS
Amazon
SNS
Amazon
DynamoDB
AWS
Lambda

SQS
Lambda #1
TimeStamp CognitoID Acknowledged
